我尝试使用Android开发者网站上的Android蓝牙聊天示例连接两台设备.它仅从其中一个设备连接,当我尝试从另一个设备连接时,它没有连接并弹出消息"无法连接:[此处的设备名称]"

我想知道我是否在两个设备上使用相同的代码,为什么只从一方进行连接,而另一方拒绝连接？

我有2个设备 - 1个运行版本2.2和1个运行v2.3.3.我的请求总是从运行2.3.3的Galaxy Y发送到运行Android 2.2的Galaxy fit-v,但反之亦然.任何人都可以帮助我,或根据下面的代码给我建议...

@Override
public void onActivityResult(int requestCode, int resultCode, final Intent data) {

    switch (requestCode) {
    case REQUEST_CONNECT_DEVICE:

        // When DeviceListActivity returns with a device to connect
        if (resultCode == Activity.RESULT_OK) {
            FaceCardList.requestConnection = true;
            FaceCardList.deviceSelected = false;

            address = data.getExtras().getString(DeviceListActivity.EXTRA_DEVICE_ADDRESS);              

            device = FaceCardList.mBluetoothAdapter.getRemoteDevice(address);

            // Attempt to connect to the device
            FaceCardList.mChatService.connect(device);
            // Get the device MAC address
        }
        break;
    case REQUEST_ENABLE_BT:
        // When the request to enable Bluetooth returns
        if (resultCode == Activity.RESULT_OK) …

我正在尝试在Web Api中启用OData..我创建了一个appanyment类OData路由,以及一个继承自ODataController的控制器,我想在控制器中调用我的Get方法.

码:

public class Appointment : IMongoEntity
{
    public ObjectId Id { get; set; }
    public Company Company { get; set; }
    public DateTime Time { get; set; }
    public DateTime LastModified { get; set; }
    public string Remark { get; set; }
}

public class AppointmentController : ODataController
{
    private readonly MongoCrud<Appointment> _mongoCrud;
    public AppointmentController()
    {
        _mongoCrud = new MongoCrud<Appointment>();
    }


    [EnableQuery]
    public IQueryable<Appointment> GetAppointment()
    {
        return _mongoCrud.GetAllEntities();
    }
}

路由:

public static void Register(HttpConfiguration config)
{
    // …
